# CSDN vs 校园应急广播

The clearest difference is in-app purchases: 校园应急广播 at none against CSDN's 10. 校园应急广播 also leads on ads (none vs shown) and iOS requirement (10.0 vs 15.1). CSDN's advantage is update cadence (weekly vs every 2 months) and chart position (#130 vs unranked). On price and device support there is nothing between them.

Both are free to download. CSDN sells 10 in-app purchases, starting at $12.99 per month. 校园应急广播 asks for nothing beyond the download.

CSDN ships an update weekly, 校园应急广播 every 2 months. The most recent releases landed on November 6, 2026 and November 4, 2026 respectively.
